Exacerbations of COPD have a large winter peak in temperate climates, accounting for much of the increased “winter pressures” of increased medical hospital admissions 39. It may be better to follow-up all patients who have violated trial treatment restrictions to the planned end of the trial. These results have been supported by database studies 45, which also show that the risk of death is reduced in those picking up regular prescriptions compared with less regular treatment 46. Other risk factors may include: 1. indoor air pollution (such as solid fuel used for cooking and heating) 2. outdoor air pollution 3. occupational dusts and chemicals (such as vapours, irritants, and fumes) 4. frequent lower respiratory infections during childhood.Many cases of COPD are preventable. As stated, the exacerbation of COPD can, and often does, lead to acute respiratory failure, but not every episode of respiratory failure in COPD patients is caused by an exacerbation. Acute exacerbations are also called COPD “attacks” or “flare-ups.” These COPD attacks can be very frightening for the patient, especially because they can happen so suddenly. 2003;21(41 Suppl):46s–53s.
